The author reviews the present status of the field of new acceleration concepts, as presented at the Lake Arrowhead workshop, held at the beginning of 1989. It is pointed out that the field of advanced accelerator concepts has seen a remarkable progress during the last few years. Plasma and wakefield acceleration has been demonstrated. One can foresee similar progress in the area of laser acceleration when the Brookhaven ATF starts operation. Ideas for using plasmas to focus particle beams and to produce beam neutralization at the interaction point of a collider have also been developed. It is further noted that the development of high-brightness beams and high-gradient linacs can also have, in the near future, a strong impact on other fields, such as FELs (free-electron lasers) and synchrotron radiation sources.
